Professor Hoh Peter In's research lab specializes in cybersecurity, blockchain technology, and intelligent defense systems, with a focus on enhancing national security through advanced information technologies. The lab explores secure and transparent data management using distributed ledger technologies—particularly Ethereum—for critical applications such as cadastral surveys and military cloud computing. It also investigates the integration of artificial intelligence and automation in intelligence analysis and law enforcement surveillance, especially in dynamic, mobile network environments. Additionally, the lab addresses challenges in scalable and sustainable blockchain systems, including energy efficiency and transaction throughput in cryptocurrencies like Bitcoin.

The military of the Republic of South Korea applies infrastructure as a service (IaaS) cloud-computing technology and applications distributed nationwide are transferred to two defense-integrated data centers (DIDCs). However, to improve the quality of the military information service provided by the DIDCs, it is crucial to expand the cloud-computing service from IaaS to the software as a service (SaaS) level. Owing to the in-house planning, development and operation of military applications by
The Ministry of National Defense of South Korea is currently acquiring various surveillance and reconnaissance assets to improve its independent surveillance and reconnaissance capabilities. With the deployment of new strategic and tactical surveillance and reconnaissance assets, the amount of information collected will increase significantly, and military intelligence capable of handling greater complexity will be needed to process such information. As a consequence, it will no longer be possib
When surveying national reference points using a global positioning system (GPS), appropriate work regulations pertaining to the surveying time must be observed. However, such data can be modified easily, so identifying non-compliance with work regulations and forgeries is challenging. If such incidents occur in cadastral surveys, it may result in financial damages to stakeholders, such as citizens and the state. Therefore, it is necessary to improve the reliability by ensuring the integrity of
After the 9.11 terror attack, lawful Interception (LI) has emerged as an important tool for anti-terrorist activity.Law enforcement agents and administrative government bodies effectively monitor suspicious target users of permanent IP-based network devices by LI in Packet Data Networks (PDNs).However, it is difficult to perform LI in monitoring migrating users from a location to another, who change their IPs due to the proliferation of portable Internet devices enabling 3G IP Multimedia Subsyst
Describes the application of the WinWin paradigm to identify and resolve conflicts in a series of real-client, student-developer digital library projects. The paper is based on a case study of the statistical analysis of 15 projects and an in-depth analysis of one representative project. These analyses focus on the conflict resolution process, stakeholders' roles and their relationships to quality artifacts, and tool effectiveness. We show that stakeholders tend to accept satisfactory rather tha
Bitcoin, which has been used for 13 years, has a role in transactions and investments as a major cryptocurrency. However, as the number of users increases, Bitcoin faces difficulties, such as scalability for transaction throughput and energy-consumption problems due to the concentration of the mining pool. When Bitcoin first started to come out, it began to develop gradually through the mining of individuals. Nevertheless, as the price of the cryptocurrency gradually climbed, large mining corpor
